DOCUMENT:Q105026 07-OCT-1993 [W_NT] TITLE :Disklock Is Not Compatible with Windows NT PRODUCT :Windows NT PROD/VER:3.10 OPER/SYS:WINDOWS KEYWORDS: ---------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT operating system version 3.1 - Microsoft Windows NT Advanced Server version 3.1 ---------------------------------------------------------------------- You are unable to access Windows NT when you use Fifth Generation Systems Disklock. Disklock is a data security application that uses password protection and an optional data encryption scheme to keep your computer secure from unauthorized access. If you run the Disklock installation program from within Windows NT, it will fail with an "‘Unable to locate physical sector’" error message. Disklock installs correctly from MS-DOS even if Windows NT is installed on your system, but when you attempt to start Windows NT, you will receive a stop screen with the following message: ***STOP: 0x0000007B INACCESSIBLE_BOOT_DEVICE Disklock must be removed (uninstalled) to be able to open Windows NT. This is a design feature of Disklock because it modifies the Master Boot Record on your hard disk drive so that it is unreadable unless DISKLOCK.SYS is loaded from CONFIG.SYS and the correct password is supplied. The Disklock product included here is manufactured by Fifth Generation Systems, a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability. For more information on Disklock, please call Fifth Generation Systems Technical Support at (504) 291-7283.
